V 8 Claims. (01. 221-148) This invention relates broadly to fitments for come apart or become separated, resulting in bottles and the like, and moreparticularly to fitinconvenience. merits comprising a closure member for the bottle I provide a fitment obviating the disadvanor the like and an applicator adapted to extend tages above mentioned. I make provision for within the bottle. For example, a fitment of clearance between the periphery of the flange of this character is disclosed in my reissue patent the rubberpart and the interior of the skirt No. 19,520, reissued April 9, 1935. of the cap and also, infitments in which the In my said reissue patent there is disclosed a rubber part extends through a perforation or unitary fitment having an applicator of the type hole in the cap, for clearance between .the por- 10 comprising a rubber bulb member and a dropper tion of the rubber part lying immediately within 10 tube engaged therewithin and extending downthe hole and the edge surrounding the hole but wardly therefrom in which the rubber bulb memwithout the disadvantage that the cap and apber fits tightly within the cap, either at the plicator or rubber part will come apart in ordiperiphery of the flange of the bulb member or at nary handling of the fitment.

In the accompanying drawing I have shown a present preferred embodiment of the invention, in which L igure 1 is a central vertical cross-sectional view through a bottle having a fitment applied thereto;

Figure 2 is an exploded view of the fitment; and

Figure 3 is an elevational view of the fitment having the parts thereof assembled and with the capin central vertical cross section.

Referring more particularly to the drawing, there is shown a glass bottle 2 having a reduced neck 3 provided with the usual external screw threads 4. Applied to the bottle is a fitment designated generally by reference numeral 5 and which comprises a bottle cap 6 shown as being made of sheet metal and which comprises a skirt portion 1 which is interiorly threaded to adapt it to be screwed down on the neck of the bottle and a top portion 8 adapted to overlie the top or rim of the bottle. In theparticular form shown in the drawing the top 8 of the cap 6 has a circular central opening 9 therethrough which loosely receives the upper portion III of a rubber part or bulb member designated generally by reference numeral II and which also comprises an outwardly projecting annular flange l2 lying within the skirt portion of the cap and against the under side of the top portion thereof. The flange I2 is loosely received within the cap. The flange I2 has a central hole 13 therethrough which communicates with the interior of the portion of therubber part ,or bulb member, and opening into the wall surrounding such hole is an annular recess I4 adaptedto receive an outwardly extending annular flange I5 at the upper extremity of a hollow glass dropper tube I6, whereby the dropper tube is held in assembled relationship with the bulb member. 7

Clearance I1 is provided between the periphery of the flange l2 and the interior of the skirt of the cap and clearance I8 is provided between the periphery of that part of the. portion H) of the bulb member which lies immediately within the .hole 9 when the parts are assembled and the material of the cap surrounding the hole. Thus the fit between the rubber part or bulb member, and, consequently, the applicator, and the cap is relatively looseand such that in the absence of some provision to the contrary the applicator and cap will not remain together as a unit at all times. However, thefclearance provided at l1 and I8 allows for substantial swelling-of the rubber before binding between the rubber and the cap or cutting of the rubber by the material of the cap surrounding the hole 9 will occur. Such clearance may be made as great or as small as may be deemed desirable. A relatively small clearance is shown in the drawing.

There is provided a liner or washer I! in the form of a perforate disc which is shown as comprising a paper backing and a protective fac ing 2| of suitable material as, for example, tin The backing and facing materials may be connected by any suitable adhesive. .The liner 19 has a central circular hole 22 therethrough, which hole is preferably of such size as to snugly receive the dropper tube H5. The diameter'of the liner I9 is greater than the diameter of the flange l2 and in fact is preferably made slightly greater than the internal diameter of that part of the skirt portion of the cap within which it is adapted to lie for a reason which will presently appear.

, shown in Figure 3 inordinary usage.

fitment is applied to the bottle the outer portion,

The parts of the fitment are assembled. as shown in Figure 3, the portion 10 of the rubber part or bulb member being introducmil through the skirt portion of the cap and through the hole 9 in its top until the upper surface of the flange l2 lies against the lower surface of the top portion 8 of the cap. The liner l9 is slid over the dropper tube l6 and is also introduced into the skirt portion of the cap until it lies against the lower surface of the flange l2. As the diameter of the liner is at least as great as and preferably slightly greater than the internal diameter of the I skirt portion of the cap, the liner fits frictionally within the cap and is under transverse pressure. The liner is preferably made of material of sumcient stiffness to withstand the pressure to which it is normally subjected in use. The liner as a whole maybe slightly bowed upon insertion into the cap or the edge of the liner may be somewhat curled. Any such bowing or curling, however,

would be very slight.

The liner I9 cooperates with the flange l2 of the rubber part and with the cap to maintain the cap and applicator together whereby to adapt the fitment to be handled as a unit. The parts of the fitment will remain together substantially as When the and serves to seal the bottle. This alsoserves to maintain the liner in proper position within the cap.

In addition to maintaining the cap and applicator together as a unit the liner l9 also has the further advantage that it shields the contents of the bottle from the rubber. This shield will ordinarily be quite effective, although some of the contents of the bottle will probably ultimately seep'through and contact the rubber. However, th re is less likelihood of the rubber contaminating the contents of the bottle than were the latter not used. Furthermore, if the bottle is used for containing an oily substance the liner protects the rubber from the oily substance.

While I have shown and described a present preferred embodiment of the invention, it is to be distinctly understood that the same is by no means limited to such embodiment but may be otherwise variously embodied within the. scope of the following claims.

I claim:

1. A fitment for bottles and the like comprising a closure capfor the bottle, the cap having a hole in its top, and a flanged applicator havingan upward extension within the hole in the cap and a flange extending loosely, within the cap, the applicator being adapted to extend within the bottle when the cap is'applied thereto, the fitment having means separate from thecap and from the applicator engaging the bottom of the applicator flange maintaining the cap and applicator together whereby to adapt the fitment to be handled as a unit, said last mentioned means being so constructed and arranged as to seal the bottle when the fitment is applied there- 2. A fitment for bottles and the like comprising a closure cap for the bottle, an applicator having a flange extending within the cap, the applicator being adapted to extend within the bottle with the flange overlying the bottlerim when the cap is applied to the bottle, and a liner underlying the flange and engaging the cap to maintain the cap and applicator together whereby to adapt the fitment to be handled as a unit, the liner being so constructed and arranged as to seal the bottle when the fitment is applied thereto.
